we know create "common" pointer function can example: void fun(); void (*ptr)() = fun; the name of function address function start. not need use address operator & this: void (*ptr)() = &fun; now pointer member function on contrary must use address operator. example class pointer member function ptr , function fun() must write: void(a::*ptr)() = &a::fun; why difference? it because function defined inside class. pointer member function holds "relative address" of function in class layout , have access way. in case of static, has no pointer , behaves global function , so, can access normal function pointer.
